DuraForm® HST

About
Applications Functional prototypes and end-use parts that require high stiffness and/or elevated thermal resistance Typical Applications include: UAV structural components Housings and enclosures Impellers Connectors Consumer sporting goods Features High specific stiffness Elevated temperature resistance Anisotropic mechanical properties just like fiber-filled, injection molded materials Non-conductive and RF transparent Easy-to-finish surface Benefits Functional prototypes can be tested in “real life” environments Complex end-use parts can be economically manufactured in low-to-medium volumes Excels in load-bearing applications at higher temperatures Attractive surface finish&&
